: way of: introduction. it is to -be pointed out that one form-of the-invention 'isseen in Figures 1 and 3, another form inFigure 6, and-the third form in Ei'gure'7.

respect too' i igures I and" 3 base'r'neans; In other-words, there is 'a simple base ilr Figure 1 'forexamplean'd a somewhat more complicated base inii igure 7; the latter becomprehend: both arrangements in a generic sense and hence the truck is covered broadly as *basemeans andvi'saslmple platein Figure 1.

Confining-"the description, at'this stage to said base: means? and: having reieren'ce' first to Figuresland 3;.it'l will be seen that said means is generallywdenoted in Figures 1 and-'3 lo'y the nutang-mar" plate o'fappropriate material and size, the platefibeing denotedby. the numeral H. The

upright means: at -theright-han'd end comprises matches 4 3 :forming keeper' seats. The laterally di'rected low'er' end: portions 1 4 are attached to theiplate 1 :li 7 I Iiie baserrnreans shovv n in is as beforerstate vs :fdrm lo'f a portable truo'k fthe saxne being-generally denoted by the" numeral 1 l'5; v Ilhe truck =c'ompri's'e's an 'openwor'k frame ineluding: longitudinal members It and transverse? end members FM audit.

7 as compared to Figure 7:, it: will 1 be noted that the only variation in: the complete assemblage: has to do with the Figures 7-, 8 and '9 l I Suitably mounted casters: file are-provided atthe' respem tive corner portions. A pair of channel irons 20 and 2| are connected to the frame structure at one end and extend perpendicularly and function as tire guide and positioning posts. The numerals 22 designate idling rollers mounted at corresponding ends in the posts 20 and 2| and mounted for rotation at opposite ends in suitable fixtures 22a on the side frame members IS. The same uprights are used on this truck as are used on the base plate in Figure 1. Here again, I employ, as before stated, a pair of duplicate L shaped brackets. The vertical portions Ha are provided with seating and keeper notches |3a and the lateral ends I la are secured rigidly to the cross-piece or end member-l8.

It will be noted that the description is being prepared to bring out the fact that the base means I0 is broadly equivalent to the base means l5 and that in both arrangements notched L-shaped brackets are provided in the base means to constitute the uprights for adjustably supporting the friction jack. It is felt, in this connection, that since the friction jack and parts immediately as-- sociated. therewith constitute a phase ofthe invention which is the same in both Figures 1 and '7. it is proper to identify the parts by like reference numerals, this to bring out the fact that 'said' parts are identical.

I make no claim to the friction jack 23, for which reason the structural details have not been specifically illustrated. Perhaps however, itis novel to provide such a jack with an adapter 24- having end keeper pins or. lugs .25, these to be adjustably associated with the selectively usable keeper notches in the aforementioned base'supported uprights. The jack includes a detachable rod-26 fitting into a suitable socket and functioning as an operating lever.

The thrust device 21. comprises a rod 28 adjustably mounted and held in the jack and a head plate 29 having a socket 30 fitting on the rod and held in place by a set-screw.

The electrical heater, which .may be of any type, is denoted, generally speaking, by the numeral 3|. I make no claim to the casing 32 and the internal electrical heating elements, therefore, I have not shown said elements. I simply claim the use of a heater of this type having a backing plate 33 with assembling and'retention and suitably ofiset flanges 34 to permit said unit 3| to be slidably and separably mounted on said plate or head 29.

The pressure block, an aluminum casting, is denoted by the numeral 35 and is designed to fit in flat firm contact with the casing 32, the same having an L-clip 35 held in place by a set-screw 31. This provides a suitable clip or hook to detachably mount the block on the heating unit 3 I The side 38 coming in contact With the tire casing 39 is of concaved form to fit the contour of the wall which is to be repaired. It is necessary to employ a number of such blocks with varying contours to meet differing situations, as is'obvious.

Coming now to Figure 6, this shows a simple.

spotter for making a repair in the tread of a tire casing. It comprises a pressure block 35a which is detachably clipped to the heater unit 31a. The unit here is the same as that shown in the other figures and includes a backing plate 33a with assembling flanges (not shown) to accommodate a ground contacting plate 40. The plate is provided with a clearance groove 4| to accommodate the current conducting wire 42. In this form of theinvention, the device is interposed between I performed as is customarily done by persons fahorizontal miliar with car repairing requirements.

In the form of the invention illustrated in Figures 1 'to-3, itwill be seen that the repair is made while the tire is on the wheel of the truck or other vehicle. The wheel is simply run over one end of thebase plate H as shown in Figure 3.

Then the parts are brought into position as here shown, this through the medium of the aforementioned friction jack. Inasmuch as the drawings are highly illustrative, it is thought unnecessary todwell upon the operation other than to explain that the blockis brought against the spot to be repaired, by way of the thrust device 21, the jack means 23 and the heating device or unit 3! carried by the head of the thrust device. Of course, the jack is properly positioned by locating the journals or lugs 25 in proper notches in the uprights on the base means. Other than this, it is felt that a descriptionof the operation is not necessary. However, in connection with Figures 7 and 8, it will-be seen that the rollers on the truck base means l5, that is the rollers 22, facilitate holding the heavy tire in place. The tire is repaired either in a vertical position as shown in Figure 8 or in horizontal position as shown in Figure 9." The posts 20 and 2| facilitate holding the tire in place and a filler device; or core 43 is placed in the tire casing at the desired spotting point. a

It is evident that whereas'the means of Figures 1 and 3, and the means of Figure 6, serve to make repairs while the tire is on the wheel, the means shown in Figures 7 to 9 inclusive is such as to permit the repair job to be accomplished with the tire casing removed from the wheel. It is evident too, that the posts 20 and 2 I, as shown in Figures 8 and 9, constitute serviceable elements in properly handling the tire 39a in both vertical and positions. Suitable ramps (not shown) may be employed to facilitate rolling the heavy tire on and off the base means I5. I

A careful consideration ofthe foregoing-description in conjunction with the invention as 1 illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty sufficient to clarify the construction of the invention as hereinafter claimed. v

'Minor changes in shape, size, materials and rearrangement of parts may be resorted to in actual practice so long as no departure is made from the invention as claimed.

I claim:

1. A tire spotter of the class described, comprising a relatively large and flat rectangular base plate, said plate being of an area sufficient to accommodate and. seat a heavy-duty tire while the latter is still mounted on the vehicle, said plate being free of obstructions throughout the major median as well as one end portion to permit said median and end portions to he slid between the ground and. tread of said tire when the latter is slightly jacked above the IOund, said plate being then anchored against slippage so long as the tire and attending vehicle weight rest thereon, a pair of uprights attached and rising vertically from the end portion of said plate opposite to that first mentioned, a jack adjustably supported on said uprights, and a pressure providing thrust device, said thrust device including a head and rod, said rod being operatively mounted on said jack, and an electrically heated hot plate comprising a casing having a fiat backing plate provided with spaced parallel offset assembling and retaining flanges, 7

adapted to be slid between a floor and tread of the mounted tire when the latter is slightly jacked above the floor, said base being capable of partly seating the tire when the latter is lowered to the floor and the co-acting load of the vehicle comes to rest thereon, said base being provided with rigid upright means at one end, a jack disposed in end thrust relation with said upright means, and a hot plate carried-by said jack and adapted to be pressed and held by the latter in working contact with said tire.

3. A spot vulcanizer for repairing tires while mounted on a vehicle comprising a base, upright means rigid with and rising from an end portion of said base and adapted to be spaced from an adjacent side wall of said tire, a jack, engageable at its outer end with said upright means, and a spot vulcanizing hot plate operatively connected with said jack, and a thrust block separably scribed a horizontally elongated base adapted to rest level and firmly'on a floor, said base being adapted to seat a heavy-duty tire while latter is mountedon a vehicle, being free of injurious projections and obstructions and being anchored in place between the floor and tire when load of the latter is superimposed on said base, upright means rigidly mounted on an outer end portion of said base, a hot plate to contact an injured portion of said tire, and an adjustable end thrust device to hold said hot plate in operative position, said upright means serving to locateand adjustably support the outer end of said thrust device.
